Thanks a lot for the contribution, @theloneexplorerquest

We have a long standing policy of not including features still behind feature gates, because there is no mechanism available on the Kubernetes API for the provider to query whether the feature gate is on or off and it would lead to unexpected errors on clusters that don't have the feature on.

As I mentioned, we appreciate the contribution and would love to merge this once the feature becomes universally available. Please feel free to keep the PR up to date going forward.

Thanks!

Hi @alexsomesan ,

Thanks for the update, I will keep this open and wait until this feature become universally available (and do more testing at that time!).
